🗑
|
||||

||||
| show | with antibodies that bind to viral protein (spike proteins on envelope) and with cytotoxic T cells
🗑
|
||||
| viriods | show 🗑
|
||||
| prions | show 🗑
|
||||
| show | either an injection of antibodies or an injection of a nonpathogenic virus with the same capsid or envelope so host immune system can create its own antibodies
🗑
|
||||
| show | viruses can continue to thrive in another animal thus maintaining the ability to reinfect the human population
🗑
|
||||
| prokaryotes | show 🗑
|
||||
| archea | show 🗑
|
||||
| show | 1 of 2 domains of prokaryotes
🗑
|
||||
| phototrophs | show 🗑
|
||||
| show | organisms that acquire energy from oxidation of organic or inorganic matter
🗑
|
||||
| show | organisms that are capable as using CO2 as their sole source of carbon - energy expensive process
🗑
|
||||
| show | use preformed organized molecules as their source of carbon
🗑
|
||||
| prokaryotic DNA | show 🗑
|
||||
| prokaryotic ribosome | show 🗑
|
||||
| show | granules of organic or inorganic matter; sometimes bound to membrane
🗑
|
||||
| flagellum | show 🗑
|
||||
| show | invagination of plasma membrane, unknown function, and may or maynot be present in a prokaryote
🗑
|
||||
| show | can attach bacteria to solid surface
🗑
|
||||

🗑
|
||||
| liposome | show 🗑
|
||||
| integral membrane protein | show 🗑
|
||||
| peripheral membrane protein | show 🗑
|
||||
| show | model describing the plasma membrane - forces holding membrane together are intermolecular so membrane is fluid - so its parts can move laterally but not separate
🗑
|
||||
| show | cholestroal
🗑
|
||||
| show | hopanoids - reduce fluidity of the membrane
🗑

|
||||
| passive diffusion | show 🗑
|
||||
| transport/carrier proteins | show 🗑
|
||||
| show | mechanism used by transport proteins to help specific molecules across membrane down electro-chemical gradient; often relied on for glucose supply in human cells, and makes membrane selectively permeable
🗑
|
||||
| active transport | show 🗑
|
||||
| secondary active transport | show 🗑
|
||||
| big and polar molecules will be transported across a membrane with... | show 🗑
|
||||
| show | protoplast then bacterial envelope then cell wall
🗑
|
||||
| functions of bacterial cell wall | show 🗑
|
||||
| show | aqueous soln of their cytosol contains more particles than the aqueous soln surrounding tissue
🗑
|
||||
| cell is isotonic to their soln meaning .. | show 🗑
|
||||
| cell is hyptonic to their soln meaning .. | show 🗑
|

🗑
|
||||
| peptidoglycan | show 🗑
|

🗑
|
||||
| gram positive bacteria | show 🗑
|
||||
| gram negative bacteria | show 🗑
|
||||
| show | can protect bacterium from phagocytosis, dessication, some viruses, and some componanets of host immune systems
🗑
|
||||

🗑
|
||||
| conjugation | show 🗑
|
||||
| transformation | show 🗑
|
||||
| show | uses the capsid of bacteriophage tin inject bacterial DNA into cell instead of virulent viral DNA (vector)
🗑
|
||||
| show | conjugative plasmid creates the sex pilus to connect two bacteria and allow passage of DNA - strand is replicated as it is separated, fed into pilus into other cell
